[0002] An endoscope is a mechanical device with a structure such as an image sensor, an optical lens, and a light source illumination. Taking a gastroscope as an example, a gastroscope can enter the stomach and duodenum through the oral cavity for observing, diagnosing, and treating the lesion site. Generally, after the gastroscope enters the digestive tract, the optical lens mainly collects images in the digestive tract. To ensure clear images, the endoscope needs to have an illumination function. At the same time, during the detection process, the endoscope also needs to supply water or gas to assist in collecting images of the lesion site, and the water or gas sent into the body may need to be aspirated in time, etc. Therefore, the endoscope needs to integrate structures with multiple functions.

One end of the image transmission optical fiber 141 extending out of the second interface section 120 is used to connect to the endoscope body. When the lens module of the endoscope receives an image signal, the image signal is converted into an optical signal by the optoelectronic conversion module in the handle, and then transmitted to the host by the image transmission optical fiber 141.
[0042] In this embodiment, in order to reduce damage to the joint of the image transmission optical fiber 141, a protective glass is provided on the end face of the end of the image transmission optical fiber 141 extending out of the first interface section 110.
[0043] Please refer to Figure 3 cooperate with Figure 5 , further, a light guide and illumination interface houses a light guide and illumination assembly 150 protruding from the surface of the first interface section 110.

One end of the light guide optical fiber 152 extending out of the second interface section 120 is used to connect to the endoscope body. When the light guide optical fiber 152 connects the endoscope and the host, the light emitted by the host is transmitted to the front end of the endoscope through the conduction of the light guide optical fiber 152 to provide illumination for the imaging of the endoscope.
[0045] In this embodiment, in order to protect the light guide optical fiber 152, a protective glass is also provided on the end face of the end of the light guide optical fiber 152 extending out of the first interface section 110.
[0046] Please refer to Figure 3 cooperate with Figure 6, Further, an intake pipe 160 protruding from the surface of the first interface section 110 is accommodated in the intake interface; the intake pipe 160 extends along the direction from the first interface section 110 to the second interface section 120 and extends out of the end face of the first interface section 110, and the end of the intake pipe 160 protruding from one end of the housing is used to connect to the host machine.
[0047] In this embodiment, the image transmission optical fiber interface, the light guiding and illuminating interface, and the intake interface are arranged at intervals, and the light guiding and illuminating interface is located between the image transmission optical fiber interface and the intake interface.
[0048] Please refer to Figure 1 and Figure 2 , on the middle section 130 of the main body, a negative pressure suction interface 131, a first water supply interface 132, a second water supply interface 133, a side leakage interface 134, and a grounding interface 135 protruding from the surface of the middle section 130 of the main body are provided. The negative pressure suction interface 131, the first water supply interface 132, the second water supply interface 133, the side leakage interface 134, and the grounding interface 135 are evenly distributed at intervals on both sides of the middle section 130 of the main body, that is, the interfaces on the middle section 130 of the main body all intersect with the axial direction of the endoscope light guiding part 100.
[0049] In this embodiment, one end of the first water supply interface 132 protruding from the housing is used to connect to an external water bottle. The first water supply interface 132 is located on the side close to the air inlet, and a gas-water control valve is connected to the end of the first water supply interface 132 extending into the housing. The gas-water control valve is connected to the endoscope body through a pipeline, and one end of the intake interface located inside the housing is communicated with the gas-water control valve through a hose.
[0050] The gas pumped in from the host machine enters the gas-water control valve through the air inlet and the hose. It can be controlled by the gas-water control valve whether the gas directly enters the endoscope along the pipeline, or the gas passes through the first water supply interface 132 and enters the water bottle connected to the first water supply interface 132, so as to pump the water into the pipeline and send it to the front end of the endoscope.
[0051] On the same side of the main body middle section 130 as the first water supply interface 132, there are also a side leakage interface 134 and a grounding interface 135.

The grounding interface 135 is connected to the entire internal metal mesh inside the endoscope, which not only ensures the electrical energy safety of the patient but also ensures good shielding performance. The side leakage interface 134 can be used to detect the sealing performance of the endoscope inner cavity. Since some endoscopes can be reused, the endoscope needs to be cleaned and disinfected after each use. However, during the use of the endoscope, it is necessary to ensure that the inner cavity of the endoscope is a completely enclosed structure. Assuming that water enters the inner cavity during the cleaning and disinfection process of the endoscope, an air pump can be directly connected to the side leakage interface 134 to detect whether water or air enters the endoscope. When the external air pump is unplugged, the inner cavity of the endoscope is closed and isolated from the outside world to prevent gas and liquid from entering the inner cavity.
[0052] Please refer to Figure 1 Cooperate with Figure 6 , the second water supply interface 133 is located on the main body middle section 130 near the image transmission optical fiber interface, and on the same side as the second water supply port and arranged at intervals, there is also a negative pressure suction interface 131.

[0054] After the negative pressure suction interface 131 is externally connected to a pipeline, blood, etc. in the human inner cavity can be sucked out of the body to facilitate the smooth progress of the operation.
[0055] Please refer to Figure 1 , the second interface section 120 is provided with an optical fiber outlet 121. The optical fiber outlet 121 is configured to be connected to the light guiding optical fiber 152, the image transmission optical fiber 141, and other water supply or air supply channels of the endoscope body, and all extend out of the second interface section 120 and extend into the endoscope.
[0056] Please refer to Figure 2 , the circuit interface 113 is used to connect to the interface 200 of the host. An electrical connection component is provided on the interface 200 of the host, and the electrical connection component contacts the current interface to achieve power supply.
[0057] In this embodiment, a clamping portion 180 is provided at the connection between the first interface section 110 and the main body intermediate section 130. The clamping portion 180 includes a limiting member 181 and a rib 182. Both the limiting member 181 and the rib 182 surround the connection between the first interface section 110 and the main body intermediate section 130, and the limiting member 181 is located at one end close to the main body intermediate section 130; the limiting member 181 and the rib 182 are arranged at intervals to form a clamping groove 183, and a chamfer is provided on the clamping groove 183 to facilitate the steel ball 210 on the connector of the host to be snapped in, so as to realize the stable connection between the connector and the light guide portion 100 of the endoscope.
